Title: Improvements in projection printing-apparatus
IPC: G03B27/475
Filed: 1931-11-20
Abstract: 392,610. Printing sound-films or combined sound and picture films. UNITED RESEARCH CORPORATION, 39, 38th Street, Long Island City, New York, U.S.A. Nov. 20, 1931, No. 32236. Convention date, June 10. [Class 40 (ii).] In projection prihting-apparatus for films, the power required for driving the films in printing relation is derived from the tension of one of them. In the construction described, two toothed discs 12, 13, Figs. 1 and 2, are freelv mounted on a stub shaft 11 fixed to a panel 10 and engage the negative and positive films 27, 28 at diametrically opposite parts of their periphery for moving the films in opposite directions. The projecting lens is mounted adjustably in the shaft 11 and the. image projected on the positive film may be viewed by a prism 62. Where 1 : 1 printing is desired both films are engaged with the discs 12, 13 on the same pitch circle. Where enlargement, or reduction is desired, sprocket members 20, 21 of smaller diameter are disposed on adjacent faces of the discs to engage the smaller film. Both films are driven positively by sprockets 30, 31 which are interconnected either, by geared shafts or otherwise -to have a speed ratio corresponding to the printing ratio. A heavy guide roller 55 on the tension side of one of the film loops serves to take up vibration or irregularity of movement. A number of printers may be arranged in series to enable a number of copies to be made simultaneously of the same negative. Alternatively, a composite record, such as a picture and sound record, may be printed on a single positive film from two separate negatives. In the apparatus shown, the aperture gate 42 is preferably provided with springs 86, Fig. 8, for holding the film in contact with the sprocket discs, and with a dovetail slot 88 in which may be adjustably clamped a filter for modifying the printing light as required. Where the negative carries a picture and sound record, the filter may be made of two parts corresponding to the width of the records, and further modification may be obtained by providing a separate light source 95 for the sound record part of the film. The lamp preferably consists of a cylindrical bulb 75, Fig. 5, with a straight filament 72 disposed eccentrically thereto so as to enable it to be placed near the aperture gate. The filament has a rigid support 73 and resilient support 74. The lamp casing 59 consists of a fixed cylinder with a slot facing the aperture gate and an adjustable inner lining having a number of slots of different widths. A lightshield 106, Fig. 10, may be mounted on the stub axle 11 between the sprocket discs.

Title: Improved wired broadcasting systems and apparatus therefor
Inventor: SMART DANIEL HENRY
IPC: H04N11/12
Filed: 1963-08-16
Abstract: 1,056,078. Distributing music etc.; colour television. COMMUNICATIONS PATENTS Ltd. Aug. 16, 1963, No. 32409/63. Headings H4F and H4R. In a wired broadcasting system pertaining to two colour television transmissions, there is applied to a conductive network, in respect of each transmission, a modulated carrier wave brightness information component and a modulated carrier wave colour information component. The frequencies of the carrier waves in respect of each transmission differ from each other by a multiple of the line scanning frequency and one carrier wave is phase-reversed with respect to the other at the field scanning rate. Also the frequency of the carrier wave of the brightness information component which pertains to one transmission corresponds to an even multiple of sixths of the line scanning frequency, which multiple is indivisible by six to produce a quotient which is an integer. The frequency of the carrier wave of the brightness information component which pertains to the other transmission corresponds to a different even multiple of sixths of the line scanning frequency which multiple is indivisible by six to produce a quotient which is an integer. Beats which arise due to second order distortions take the form of a relatively unobtrusive dot pattern. Preferably the two brightness information carrier wave frequencies differ by a frequency which corresponds to an even multiple of sixths of the line scanning frequency, which multiple is indivisible by six. The system is suitable for use with 625-line S.E.C.A.M. transmissions. The transmission equipment is generally similar to that described in Specification 1,055,443 but the output of the modulator 12 comprises an amplitude modulated carrier wave 15 (Fig. 2, not shown) which corresponds to an even multiple of sixths of the line scanning frequency P which multiple is indivisible by six (e.g. 2080 P/6 = approx. 5À4 Mc/s.). The frequency f 2 of the carrier wave of the colour information component (approx. 9À83 Mc/s.) is such that f 2 -f 1 is the same as that adopted for the television line standard concerned (approx. 4À43 Mc/s.). The output of the modulator 20 has a carrier frequency f 3 (e.g. 2084 P/6 = approx. 5À4 Mc/s.) in respect of the amplitude modulated carrier brightness information component and a carrier frequency f 4 in respect of the complex frequency and amplitude modulated carrier colour information component. The difference f 4 -f 3 is again the same as that adopted for the television line standard concerned. Receiver.-The description of the receiver is identical with that of Specification 1,055,443.

Abstract: 393,299. Maintaining defined speeds of motors. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Nov. 23, 1931, No. 32429. Convention date, Nov. 22, 1930. [Class 38 (iii).] Motors 1, 1<1> used alternately for rolling-up paper have their fields regulated by a regulator 3 controlled according to armature current through "shunts" 14, 14<1> so as to obtain constant tension in the paper. A. change-over switch 4 associates the armature of the operative motor with a current relay 6 which upon closing its contacts short-circuits a relay 11 to cause a pilot motor 5 to move the regulator 3 in the field strengthening direction only. Should the paper break, the regulator 3 remains in the position to which it was last moved. When the switch 4 is changed-over so as to associate the other motor with the regulator, the righthand contact of this switch causes a relay 7 to pick-up and short-circuit a relay 10 which thereupon drops and causes the motor 5 to return the regulator 3 at high speed to its initial field weakened position.

Title: Improvements in envelope making machines
IPC: B31B19/00
Filed: 1927-12-03
Abstract: 282,649. Smithe Machine Co., Inc., F. L., (Assignees of Novick, A.). Dec. 21, 1926, [Convention date]. Sheet-separators.-In a machine for making envelopes and: comprising means for removing blanks from a stack and forming them into a band with the area of the sealing flaps exposed to be gummed, means are provided for conveying the blanks whilst in the band, the means being adapted to grip the blanks positively and hold them in spaced relation. The machine is shown in elevation in Fig. 3 and in plan in Fig. 4. A sucker 10 raises the topmost blank of a stack A, retained by a presser 23, to a nozzle 11 adapted to blow it against a roller 12 associated with planetary rollers 14. These rollers feed the blanks in succession past rollers 15, 17 to pairs of conveyer bands 20, 21 between which the blanks are gripped by their wing portions a, the blanks overlapping each other with only the portions to be gummed exposed. Gum is supplied to the band as it passes a container 43, the conveyers at this point being supported by a drum 31. Midway between its ends, the drum is grooved to accommodate a stripper member 50 adapted to force out the centre portion of the blanks whilst the wing portions are held back on the drum 31 by rollers 51. As each blank clears the rollers 51, its wing portions spring outwards to the plane of the centre portion, the leading flap of which is held between the bands 21 and chain conveyers 55. The chain conveyers each comprise side links 55<c> Fig. 12, connecting block links 55a and each block link 55a carries a spring finger 55b adapted normally to press on an adjacent side link 55<c>. In approaching the envelope band, the chain conveyers pass over a guide shaft 57, Fig. 5, and the fingers 55b stand out from the links 55<c> ready to receive the wing portions of the blanks as they spring from beneath the rollers 51. The wing portions are each assisted by a separating finger 60 pivoted on an adjustable arm 62 adapted to be oscillated by a cam on the main shaft of the machine, the finger being kept in contact with the conveyer band 21 by a spring 69. The finger engages beneath the wing portions and moves them outwards positively. As the chain conveyer straightens out, the blanks are gripped between the spring fingers 55b and the links 55<c>. The conveyer moves at a slightly higher speed than the envelope band and the space between the fingers 55b is slightly greater than the breadth of a gummed flap, the arrangement ensuring that the blanks are held on the conveyer with their gummed portions spaced slightly apart.

Title: Improvements in the manufacture of articles from iron alloys
IPC: C22C38/22
Filed: 1933-11-24
Abstract: Forged or cast articles which are rust-proof and highly resistant to wear, alkalis, heat, and flame, are manufactured from iron alloys containing 0,1-2 per cent of carbon, more than 0,3 per cent but less than 1,3 per cent of silicon, 5-35 per cent of chromium, and 5,1-20 per cent of molybdenum, with or without 1-19 per cent of nickel.  If the articles are to be resistant to heat &c. in the raw forged or cast state without polishing the chromium content is between 13 and 35 per cent.  The chromium content rises with the carbon content and the molybdenum content is increased to give greater resistance to wear.  Alloys referred to contain besides iron, (a) 1 per cent of carbon, 6 per cent of chromium, 7 per cent of molybdenum, and silicon; (b) 0,4 per cent of carbon, 5,5 per cent of molybdenum, 6 per cent of chromium, and 0,4 per cent of silicon; (c) 1,3 per cent of carbon, 5,2 per cent of molybdenum, 13 per cent of chromium, and 1 per cent of silicon.  The alloys may be used, for example, in the manufacture of scissors, economiser pipes, and superheater protecting plates for steam boilers, but the manufacture of valve seats for internal-combustion engines is excluded from the scope of the invention.  Specification 103,809, [Class 82 (i)], is referred to.

Title: Improvements relating to the continuous extraction of substances from solid matter by means of a solvent
IPC: B01D11/02
Filed: 1949-12-23
Abstract: <PICT:0688690/III/1> <PICT:0688690/III/2> A process for the continuous extraction of liquids from solids, and especially oil from seeds, with the aid of solvents comprises placing the solid, preferably ground, on an endless gridded conveyer, sprinkling a solvent on to the said solid as it is conveyed and stirring the upper layer of the solid to be treated. As shown, a hopper 2 feeds ground seeds on to an endless chain conveyer 5 and the thickness of the layer so formed is adjustable by means of a gate 3.  The conveyer 5 has rollers 39 circulating on a track 40 and engaging recesses 43 in a driving drum 6 and loose drum 45 positioned at the discharge and charging ends of the conveyer respectively.  The drum 6 is driven by motors 48 or 49.  Fig. 4, through the speed reduction gear 77.  The speed of p  the conveyer is automatically controlled by the pressure of the feed exerted on a diaphragm 47, preferably of synthetic resin, which is provided in one of the walls of the hopper 2.  The diaphragm controls a mercury change over switch 50 which in turn acts through coils 74 and 75 to bring either motor 48 or motor 49 into action. The speed of one motor is twice that of the other. A second diaphragm 85 cuts out the motors as the hopper empties. Fresh solvent entering the system at 56 is sprinkled through atomizers 16 on to the exhausted seeds at the discharge end of the conveyer and, after percolating through the seed bed, collects in a tank 55, overflows at 30 into the adjacent tank 23 and is forced from the base of the tank 23 by pump 8 to atomizers 17, whence it falls on and percolates through the layer of seeds above the tank 23.  The counter-current extraction proceeds through tanks 24 to 29 with their associated pumps 9 to 13 and atomizers 18 to 22, the most highly concentrated extract at 29 overflowing into a tank 31, from which it is pumped to the solvent recovery unit.  The pumps 8 to 13 are individually regulated at e.g. 57, 58 and 59 to allow for the different permeability of the seed layer at various stages in the extraction. The atomizers consist of a feed device formed by a vertical liquid supply pipe closed at its bottom by a movable plate and positioned in the centre of a distribution means having a series of vertical bars 69, Fig. 3 (not shown), distributed in space along concentric cylindrical surfaces.  The arrangement ensures uniform distribution of the liquid over the seed area to be sprinkled.  As the seeds are conveyed above the first half of a collector tank they are sprinkled with liquid from an atomizer. During the second half of their passage above the said tank they drain.  Freely oscillating rakes 51 stir the seed bed at the limit of the zone which is sprinkled by the atomizers and in so doing form a slope which is situated in the draining zone. This arrangement prevents mixing of liquid extracts of different concentrations.  The assembly is totally enclosed and can be worked under pressure.  Specification 616,825 is referred to.

Abstract: 959,781. Analogue-to-digital converters. EPSCO Inc. Sept. 26,1960 [Sept. 25, 1959], No. 32988/60. Heading G4H. A sweep voltage 4 from a generator 1 is supplied to two comparators 2, 3 where it is compared with earth potential and a variable input voltage respectively. The order in which comparators 2, 3 produce an output pulse denoting equality of the two respective inputs indicates the polarity of the input voltage, and the time interval between the output pulses indicates the amplitude of the input signal. Bistable circuits 6, 9 are set by the outputs of the comparators and control NOR gates 18, 19, 21 so as to set bistable circuit 27 to a state indicating the polarity of the input signal and to open NOR gate 20 so as to pass clock pulses from a generator 24 for the time interval between the occurrence of the output pulses from comparators 2,3. The Specification also describes in Fig. 3 (not shown) a system for indicating when a signal representing for example length, pressure, colour or surface finish, exceeds one or other of two limits. The variable signal is applied to comparators 2, 3 in place of the sweep voltage, and upper and lower limit reference signals are respectively applied to comparators 2, 3. The state of gate 20 then indicates if the variable signal exceeds one of the limits and the state of gate 21 indicates which limit is exceeded.
